lhsa Posted June 11, 2006 Share Posted June 11, 2006 thanks to whitetiger/froggert, i am now proudly riding on JDM bilsteins rev A with JDM "Black Rock" springs. Love the ride! its only a touch stiffer and firmer than stock suspension, but the floatiness is gone! the ride is definitely softer than stock wrx sti suspension, if that provides something to measure against. the springs were supposedly for a wagon, but they feel completely natural on my sedan. the only minor negative wish that the rear rode a touch higher, but i think its just the way our suspension looks. its hard to get a butt higher look. the ride is so good that i'm keeping them on and foregoing other springs options at this time. http://i60.photobucket.com/albums/h20/LHSA-LGT/IMG_0467Large.jpg http://i60.photobucket.com/albums/h20/LHSA-LGT/IMG_0468Large.jpg http://i60.photobucket.com/albums/h20/LHSA-LGT/IMG_0469Large.jpg http://i60.photobucket.com/albums/h20/LHSA-LGT/IMG_0473Large.jpg Link to comment Share on other sites More sharing options...
LittleBlueGT Posted June 11, 2006 Share Posted June 11, 2006 Looks good. Install an extra rear ruber spring seat on the bottom of the rear springs to raise it up about 7 mm, then it will look perfect!

lhsa Posted June 12, 2006 Author Share Posted June 12, 2006 does anyone know how many miles i can reasonably last before an alignment is absolutely necessary? Link to comment Share on other sites More sharing options...
froggert Posted June 12, 2006 Share Posted June 12, 2006 depends on how far off the alignment is now. i'd get it done sooner rather than later. Link to comment Share on other sites More sharing options...
Daedalus Posted June 12, 2006 Share Posted June 12, 2006 Where can you get hand-me-down JDM suspension bits? Link to comment Share on other sites More sharing options...
lhsa Posted June 12, 2006 Author Share Posted June 12, 2006 i wish they were hand-me-downs:( once in a while, you can find JDM bilsteins for sale here. luckily for me, it was local and just in time for my install day! Link to comment Share on other sites More sharing options...
whitetiger Posted June 13, 2006 Share Posted June 13, 2006 looks good. I told you the springs would settle alittle. And it did ride very nice. Link to comment Share on other sites More sharing options...
lhsa Posted June 13, 2006 Author Share Posted June 13, 2006 ya, i'm really happy with the new suspension. the handling is slightly awkward without an alignment, but real tight. now i think i need a brake upgrade...with all the power and ride, my brakes are the weak link!

PGT Posted June 13, 2006 Share Posted June 13, 2006 Looks good. Install an extra rear ruber spring seat on the bottom of the rear springs to raise it up about 7 mm, then it will look perfect! how does this raise height if the space between the spring seats is a fixed number? All you do is increase preload (which may help height actually). You'd need to lengthen the distance between the mounting points of the shock to 'raise' the car Link to comment Share on other sites More sharing options...

You'd need to lengthen the distance between the mounting points of the shock to 'raise' the car A longer spring means a higher car, not more pre-load. The rubber spacer makes the spring like a longer spring. I know I did it on my car. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

PGT Posted June 13, 2006 Share Posted June 13, 2006 so, I assume you didn't tighten the nuts down all the way on the tophats then? Because....if you did, you added preload and didn't affect shock length (which might have the side effect of adding height). Link to comment Share on other sites More sharing options...

JK It is not like the shocks are extended out as far as they will go. OEM springs (with full weight on) sit at a certain height. iON springs (with full weight on) sit about 25 mm lower. iON springs with a spacer on sit at 25 mm lower minus the size of the spacer, which is around 7 mm, so the car sits 18 mm lower then factory, or 7 mm higher then with just the iONs alone. You cannot adj for preload on the Bilsteins. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

PGT Posted June 13, 2006 Share Posted June 13, 2006 you don't get what I'm saying do you? If the space between the lower spring seat and upper perch (tophat) is fixed, how does adding a spacer in the middle change that? On a height adjustable coilover, you adjust the spacing between the mounts, thereby adjusting height. With fixed shocks, you don't have that luxury unless you have something like Koni Yellows with adjustable perches. Link to comment Share on other sites More sharing options...

With fixed shocks, you don't have that luxury unless you have something like Koni Yellows with adjustable perches. Then how does a different spring change the height? BTW the space between the lower spring seat and upper perch is not fixed. It is very dependant on the spring (or whatever else) is in between.

rexster Posted June 13, 2006 Share Posted June 13, 2006 what are JDM "Black Rock" springs? i'm assuming they're stock JDM springs from certain model years? Link to comment Share on other sites More sharing options...
lhsa Posted June 13, 2006 Author Share Posted June 13, 2006 i think they're JDM aftermarket lowering springs. clearly they haven't found great success in the US market Link to comment Share on other sites More sharing options...
jim1969 Posted October 30, 2006 Share Posted October 30, 2006 where did you get them? Link to comment Share on other sites More sharing options...
lhsa Posted October 30, 2006 Author Share Posted October 30, 2006 they came as a set with my JDM bilsteins, but i've seen them advertised in japanese legacy mags. black rock also makes brake kits, as well. they are supposed to be progressive springs f/r from 20-30 lbs.
